Hi @Bruce Wayne ,
I don't 100% understand you.

Maybe this add-on can help:
This add-on developer is French also - maybe you can communicate with @Thibeault
Sorry - I still do not understand you.Hello and thank you for your reply sorry I am French I do not wish the ADD-ONS that you have given me, that is to say the members when it answers I want it leaves 5 words mandatory and not 20 characters .. . thank you
