Well you can easily export a file to a midserver with an OOTB export set but you are limited to locations relative from the midserver-folder. The way I've solved this in the past is to use my collegues who know windows or linux-server. I upload the file and they have created a scheduled task that moves the file to the correct folder which could be on that same server or somewhere else ofc. I've looked for easier ways myself but this seems to be the quickest tbh.

Edit: Oh sry this was for reports specifically. The above is for exporting list which might apply for you if it's list reports you are exportning
