This is possible in the 2.5.3 modeler. In the domain model the contect menu on an entity gives the option find microflow actions, from the dialog that then opens it is possible to search for commits. I'm not sure when this feature was introduced.
Right Click on the entity -> Find microflow actions...
This will allow you to find information on the microflow actions. You'll have to find commits from save buttons on forms separately though I believe.
If you go to Find Advanced (Control + Shift+ F) you can search for Microflow actions then select your entity then select change then select Yes on commit
