Managing expenses from a joint bank account

[brianrylan]

Hello, I have a joint bank account with my partner and would like to manage my expenses so that only 50% of the expenses from that account are charged to my personal statement. Sometimes I use a credit card for payments, which are then offset through the joint account.

I can calculate this expense myself using MMEX, but is there a more automated or optimized way to manage these expenses? Thanks for the support
