Track discontinued sets

[tonyinwi]

Is your feature request related to a problem? Please describe.

Would like to have an indicator of whether a set is discontinued or not. Simple Y/N flag. I'm a set guy, parts might come some day but not yet.

Describe the solution you'd like

A simple boolean that could potentially be automated from either BrickLink (I don't think they have this data?) or BrickEconomy (they do have it but no API that I can see.)

Describe alternatives you've considered
Using Comments/Remarks/Marker instead.

Additional context
I have some investment sets that are going to price lower than market until no longer retail and discontinued. Need a "smart" way to track what is still retail vs. not. Why would I sell retail and compete with LEGO etc.

I have another request I'll submit separate for a margin column - difference between cost & sell price. This will help me identify the sets I need to move, and when.

I was wrong:

This would also allow pulling the original sale price.
