I figured, when we choose modular weapons in the weapons tab in creative, we can clearly see the 4 squares that are used to show the attachments we chosed when we use the mod bench.
So I thought, why not add a tab below the squares in which we can select the mods we want
@PhantomCagney Thank you for your feedback. While I cannot guarantee a response, I can confirm that this has been forwarded to the appropriate team.
