Is it possible to only show specific multiparm instances. For example in the interface on an hda?

Whenever I increase minor version on an HDA I am working on, the most likely outcome is a an asset which is not updated, or other random complications and eventually a Houdini crash. What I mean by 'not updated' is that the python states script is not saved with the new version of the asset.
Granted this is my first HDA and I have almost no experience, but should this be so complicated?!
Can someone recommend a few guides on how to use this feature properly?!

Can someone please help me understand conceptually the difference between these two? Why or when should you make use of one or the other?
