Filtering GL reports, exporting data, and managing separate ledgers for taxation vs. internal bookkeeping in Manager

Hello; my apologies in case I ask a question that might’ve already been answered but I just don’t understand some things. I am new to the software and that is probably why.

Filtering Specific Accounts in General Ledger Transactions
I know Manager allows viewing individual accounts in the General Ledger Transactions report, but is there a way to select multiple accounts at once? For example, I want to view 12 GL accounts while excluding 3 others. Is there a way to do this within Manager, or is there a workaround?

Exporting the General Ledger & Payment/Receipt Data
How can I export my General Ledger as a CSV or any other format? Given the limited options in Manager (or just because I can’t understand them), I am considering switching to another accounting program. Having an export feature for all payments and receipts would be extremely helpful for migration. Is there a way to do this efficiently?

Managing Multiple Versions of the General Ledger for Taxation vs. Internal Bookkeeping
The business I track in Manager has certain transactions; lets say income, that is not actually income but will have to be shown as income for taxation purposes. Essentially, I need two separate ledgers with 90 percent of the same accounts and same transactions; one for taxation purposes and one for actual internal bookkeeping of the business.

The only solution I can think of is maintaining two separate businesses in Manager. However, this seems redundant and tedious. I also explored using the Division feature, but it only allows filtering by Profit & Loss or Balance Sheet, not the full General Ledger. Given the way my chart of accounts is structured, I need the complete GL for a full picture.

Has anyone found a better way to handle this? How do you deal with keeping separate records for taxation while maintaining accurate internal books?

Manager support for chart of accounts groupings optimised for taxation reports separate to COA ordered for general use is in the ideas Income tax payable

Alternatively Manager could support custom fields on COA accounts which could be used for external sorting and filtering, which is also in the ideas New Custom Fields and Chart of Account
