Modify/ Remove certain undo queues

#1

Hi everyone, are there any ways in which I could access/ edit the undo queue?

The reason I asked is because, in my current tooling, I created the following in one of my renaming function:

cmds.undoInfo(chunkName='renameChunk', openChunk=True)
# do cmds.rename operations
cmds.undoInfo(chunkName='renameChunk', closeChunk=True)

However, if I am trying to do an undo function (ctrl+z) to revert back the naming, I need to hit the key combination a couple of times instead of the expected 1 time.
And upon printing the list of undo queues, it is something like:

...
# 39:  # 
# 40:  # 
# 41:  # 
# 42:  # 
# 43: renameChunk # 
# 44:  # 
# 45:  # 
# 46:  # 
# 47:  # 
# 48:  # 
# 49:  #

And so I was thinking if it is possible to ‘remove’ these empty actions?
