Load/Extract EventHandler

Hi OneStream experts,

I was looking to understand if it's even possible to handle the load button from the Load/Extract section in OneStream using a specific EventHandlers of any kind.

I need to be able to add validations whenever a Metadata xml file is loaded through the Load/Extract to check certain things of its content without falling (as usual) in a custom development from scratch.

Hopefully someone is able to assist.

Thank you!
