Hi Gabriel,
IDK if this is useful, but we have automated creation of new revision of method and unapproval of prior rev by running Powershell with DMT. The DMT imports can also do record deletes as well as updates. It works seamlessly without any user interaction other than pushing create new rev button.
We use BAQ export to take current part method out with change needed in the method, then we bring the new method back in with new revision and unapprove the old rev.
You could use same method to BAQ export your method out removing the operation and bring it back in and approve it.
Here’s a recent post with people doing similar methodology (PS/DMT) Creating a Powershell script to run DMT
