Possible to store all data store entities in local variables?

I would like to make a confirmation with respect to the Shared Component mentioned above. To the best of my knowledge, it may be ruled out as an option. Because the use-case here talks about accumulating the Data Store Entities from all the Datasources in the given Appian instance into a storage location and searching through them, whereas the Shared Component is all about querying the Data Store Entity that is inputted to it. In-fact, querying the Entities comes at a later stage, that is, only after searching through the available Data Store Entities and choosing one of them thereafter.
