Oh oh ! I like it simple like that ! (with the profile URL last option) Thanks
I've added a condition to set personnal profile url's and company's url based on a different patern, then I concatenate the register date, first name, last name, and populate the alias field (the profile URL)
Easy and working !
One thing a bit weird is that it seems to take a bit of time to have the links properly populated, I guess there's a cache somewhere, but that's a bit surprising !
Some screenshot to help the others if needed.
