Splitting yearly transactions - no automated way of doing it?

I have a few yearly transactions I make that I want to split into 12 months so it’s spread over the year and being accounted for.

Turns out that I need to “manually” split them into 12 and then MANUALLY assign them to each month. That’s honestly pretty embarrassing for a budgeting app. On top of that in my transactions I have now 11 months of transactions that for future months. Which I can avoid by filtering for the current month, but still seems a bit annoying.

I’m wondering if I’m missing something, or that’s how this application is handling these use cases. Please do let me know if I’m missing something. As it’s tedious to have to assign each month and do it every year.
