How do I add or create different GL accounts for example if I want to add Groceries or under Motor Vehicle expenses add a sub account to split between Fuel, Installments and toll fees?

Thank you so much it helped a lot. Please assist me with another issue.
After importing my bank statement and after creating a rule, how do I get to show/see the GL account that the transactions was allocated to in the “Bank Transactions” Tab

If you Edit the transaction, you can see the account it was posted to. I think that’s the only way.

Have you read the guide to importing bank transactions?
