Compound/Grouped Attributes

[mxmeeple]

I have the need for some compound/grouped attributes but at the moment all I can do is have multiple with a shared prefix
So for example what I would currently have to do is:
~Recipe_1_Level5_Skill = Forging, ~Recipe_2_Level5_Skill = Smithing, #Recipe_3_Level10_ingredient = Stone, ~Recipe_3_Level10_Skill =Forging, #Recipe_4_Level10_Ingredient = Metal, ~Recipe_4_Level10_Skill = Smithing
Manually entering each of them is time consuming, and prone to typo's and errors
What I would love to see on the frontend is a separate form,
Which would be indicated by a new attribute definition like the following:
#grouped:GRPNAME="#LBL1,~REL2,#LBL3,multi,inheritable,promoted"

Sample mockups for the forms
