### Pitch: what problem are you trying to solve?

I'm encountering an issue with scheduled transactions where there are multiple scheduled payments for the same payee, but I want to distinguish them in the ledger with a note denoting which particular one it's for.

I originally tried to fix the issue by editing the schedule as a rule and applying a Note and Category, but I noticed this is just running the rule to match it and applying the notes and categories to the first match it finds.

In most all cases this is fine, but I have cases where there are two scheduled transactions that are from the same payee, on the same day of the month, for the exact same dollar amount. This shows up in the ledger with the same note and looks like a duplicated transaction, but they are actually separate ones and should have both notes.

This is how I have my scheduled transaction set up:

And the rule for it:

There is also a PBS Kids scheduled transaction that has the same day of month, same payee, and exact same payment amount. But when I look at the upcoming transactions, it looks like this:

There are supposed to be two transactions, but one is supposed to say PBS Kids and the other is for Curiosity Stream. However, the rule matching is identifying them both as the same one and applying PBS Kids to both.

### Describe your ideal solution to this problem

Using rules to modify the scheduled transaction does not seem like a good way to solve this. Instead, I think a more suitable solution would be to add support for adding Notes and Categories to the Scheduled Transaction template to automatically apply them without the need to rely on rule matching.

I think it would be self-explanatory in usage and purpose.
