Request: Cross-Store DLC/game ownership for Immortal Empires

Has CA/SEGA ever made a statement on this?

I own WH1 base game, some WH2 DLC and WH3 DLC on Epic games.

I own WH3 base game and some WH3 DLC on Steam.

(dont ask how this happened but asking me to buy everything again is unreasonable at best...)

pls. :(

Let us link them through a "Creative Assembly Account", I mean the damn thing already exists and even works through Epic Games' own online system anyway as far as I know, isn't that what it's supposed to be for???
