You can do anything with the remote since you have the latest version of PE 4.05.

Upload the ccf that is on the remote to your pc to save it.

As for your current query. just double click on the macro button that you want to change. The window that pops up is the list of commands within that button. You can delete any of the commands that you do not want in there, or add any that you want to. Save your changes as a different name, just in case you dont like it. This is so that you at least have the orginal ccf that the programmer made for you.
