Apologies, but I was unable to comprehend what you asked of me, but, with one draw back, in which I will elaborate on, I did manage to figure it out via a previous post, provided by @poster, passing multiple selected items to external tool - #3 by tezza
The only draw back, from the MTE below, is that I can only process/export one file at a time, regardless of when I select the files I want processed or not. Moreover, I created an "ACTION" which did not work at all, for some reason. Anyway, you or anyone in this post can tell me what I am missing in the attacked .mte below
