I have started including appendices in my thesis to collate common information for each separate \part section so as to make the script concise and to the point. I am using a KOMA-Script document class: scrreprt, using the appendix package together with the minitoc package for my chapter format style has been giving me a real headache, though it is solved (in my previously asked question) for the most part, the result was unsatisfactory as I cannot include a \minitoc inside the appendix.
My solution was to go manual and simply change \chaptername name to appendix and the and \thechapter numbering to \Alph{chapter} and subsequently also change the \setcounter so as to get the chapter lettering to start where desired.
This of course meant I had to put it all back at the end of the appendix chapter so that all following chapters would continue unaffected. I was wondering whether there is a way to simply define an environment that sets these parameters (chapter > appendix, chapter numbering > letter, chapter counter) and that allows for the chapter counter to continue between the instances of each repeated environment such that when I put my first environment at the end of the first part it will be called Appendix A and once I put the next one at the end of the second part it will automatically continue form the numbering of the previous environment resulting in Appendix B.
If there is a relatively simple way to do this by defining an environment I would gladly implement that over the manual approach I employed in the below MWE.
