Missing (I think) in-game tip about ability to transform bought PoE1 stash tabs to Merchant's Tab

Hello,

I recently reached Act 4 and met Ange. Once I acquired my hideout in order to setup the new merchant system, she told me that I needed to get Merchant's Tab.

Fast forward to this weekend where there is a sale on Merchant's tab ; I bought a few of them since there was no in-game information about the possibility to upgrade existing stash tabs bought in PoE 1 to Merchant's Tab.
This purchase has been brought to support and the ticket was quickly resolved by their CS team.

Suggestion: for future PoE1 players who already own supported tabs, I think this upgrade should be mentionned in-game by Ange.
