Is there a way to apply the cash adv to a specific expense report through an interface or api?

Summary:

In the 22D version, the functionality of manual application of advances to employees was released, however we need to replicate this same scenario in a massive way, since the client needs to apply the existing advances to existing and future expense reports individually, we are talking about an approximate universe of 10 thousand existing advances.

Could you tell us what API or bulk load functionality we can use to solve this?
