How to specify the asset type of PlanetScope image in same collection in Process API

We are ordering different asset types (analytic and analytic_sr) of Planet Scope in the same collection.
To download the image we are using process API.
How to specify the asset type in the Process API as in the current document there is no way to mention the asset type while downloading.

Is the right way to use different asset types is to maintain them under different collections?

There is currently no way to separate the type in BYOC collections, which are used for ingestion of Third party data.
You should use separate collections for analytic and analytic_sr.
With “hectares under management” model this should not be a problem as you can re-ingest all the data once again, separating it for the type.
