Ask if the following is possible and if so how.
I have created a lockscreen and linked it to a folder under which 200 Samsung S7/S8/S9 tablets are linked. 
Now it is just that some tablets must be provided with an extra button that opens a specific app on the tablet. and each tablet has a different app that is specific to that tablet.

I can make a new lockscreen for each tablet, but then I will have 200 different lockscreens.

Can this be controlled through a profile so that I can send a specific adjustment (button and link to app) to 1 tablet?

Hopefully someone has a solution for this
