The operation could not be completed

Can we please add or fix this problem. It took me 1 hour to figure out along with help of people in the lobby. Until someone found a reddit post.

The problem I was encountering was that I was trying to use a Uncut Support Gem.

Below are the details in the proper timeline.

I had 2 Uncut Support Gem. The Goal was to add to Frostbolt, Scattershot LVL 1 & Deceleration LVL 1. Mind you, they both have the same requirement.

So I used 1 Uncut Support Gem for Scattershot and added it to my Frostbolt.

Then I used the other Uncut Support Gem for Deceleration. When I clicked "Engrave" it said "The Operation could not be completed"

And come to find out after bugging multiple people and searching on forums that it was because I did not have enough Dexterity Support Gem Capacity.

So I ask that if we can add a feature explaning why the operation could not be completed. Example "You have no more Dex Support Gem Capacity" instead of "The operation could not be completed"

Thanks
