Maintaining setting of Save version

I am using su 2020

But I need to save file as 2015 version everytime

Because most of co-worker using 2015

It is too inconvenient

Is there an extention that help this problem?

Like autocad
Go into option and setting save version

Maybe Eneroth Legacy Save from the Extension Warehouse.

@indie3d 's Allsave Plugin

or Maybe @eneroth3 Newer version could help you
