Better tracking of internal transactions

Each month I find I transfer money from my savings account to my spending account to pay for activities or extra groceries. My wife may also transfer some money from her account (which is linked to Emma) to top up our spending account a couple of times per month.

At the minute these transactions are all lumped together under Excluded but I’d like to able to see transactions specifically between two accounts as their own Category.

For example Savings Account to Spending Account
Wife’s current account to Spending account
Spending account to Credit card (if money was left over at the end of the month)


Can you create a custom category for this? E.g I have a “savings” custom category that has all the transactions from my current account to savings account and vice versa
