When will the new MARBASECID variable be available?

I would like to link ASEC data to the March CPS (in addition to potentially applying answers to other months). I’ve read about the MARBASECID variable that MPC is constructuing and am wondering if it will be available soon. Thanks!

The testing process for a variable such as MARBASECID is fairly laborious, so there is not currently an official release date. However, we anticipate that the variable should become available by the end of the year.

Hope this helps.
