Porting IEC 61131 ST code: inadvertent duplication of variables

during my initial experimentation, I inadvertently duplicated all the existing variables by not excluding them from the list…
I have encountered this on the other platform which simply identified the offending variables prior to the importation process and allowed one to delete the duplicates
In this case, I was faced with an angry red screen of endless errors…
there seemed to be no way to delete the offending duplicate variables - which would seem to be the most obvious way to deal with the problem. Just being a newbie, I understand I haven’t found all the knobs yet, but something like dealing with errors should be in_the_face…
I ended up just abandoning the project - killing PLCnext and fixing the CSV and importing it on the next go-round…
I noticed that the default axc-f-2152 project was only visible on a default blank start…
I think it is prudent to figure out how to deal with stuff like duplicate variables so that when it happens I can deal with them without abandoning the editing session and „starting over“

I am hoping that there is some way to import local variables from CSV as well so I don't have to bang in all the local variables manually...
