Asset Transfer - ABT1n - how to activate button multiple assets

Hello,

I have follwing quesition:

How can I activate in function ABT1N button multiple assets.

I want to use asset transfer for a few hundred assets.

I have read that this functionality is not available in ABT1n:

ABT1N transaction the multiple asset option

Alternative could be function ABUMn - do you agree with me?

Thank you for your help and answer.
