Ability to tag rems with a property / use a property as a tag

Let’s say I have a rem “AI tool”, and I tag AI tools with it so that I can collect them all in a nice table over time.

I also want to indicate whether an AI tool is open source. So I make a rem “AI-tool feature” under “AI tools”, and define it as a Property (of type “Multi select”).

Next, I make a rem called “open source”. I would like to be able to tag this rem with “AI-tool feature”, so that it appears as an option in the Multi-select menu for all rems tagged with “AI-tool”.

Instead, I have to create another rem, let’s call it “AI-tool feature (Property)”, and then select “AI-tool feature” as the Source for “Rem With a Specific Tag” as shown below.

Properties and tags shouldn’t necessarily be different things in the first place. Some optionality to blur the distinction would help remedy that. Thanks!
