row level with external users

Hi everyone,

I'm currently configuring a Power BI account for another company. So i have several external sharing access but i also want to control which part of the data each user can access to.

I'm familiar with the row level security but for now it's not possible to configure it for external users (only user having the same mail's domain of my company).

So is it going to be possible to do it in the future or not ? Or is there another way for me to do it ?
