Automate changing part type

I have two 3mf files where the only difference between them is the Text parts type. The first file has the part type set to Modifier, and the second file has the part type set to Negative Part. There are many plates and text parts, so my current work flow is to copy the 3mf containing the Modifier part type to a new 3mf, then in the new 3mf manually change each text part type to Negative part. This is tedious and error-prone. Each Text part is in different objects, so I can’t select multiple parts to change them simultaneously.

Does anyone have suggestions on how to speed up this process? As a request, it’d be nice to have a way to automate this, like a scripting API that’ll let me programmatically change the part type. Thanks!
