Hi,
We have a use case related to #237 but slightly different.

We would like to store a second obs array ("sub-obs", where an observation is an individual transcript in a MERFISH experiment), but related to the first obs array (where an observation is an individual cell).

Has your team thought about how to deal with this use case?

I am thinking something like this:

where the transcript ID and cell ID columns in the sub-obs can be like foreign keys into the main obs dataframe.

Is it possible to add a differently-shaped obs and obsm to the same AnnData store?
