$filter on more than just partition? - Any way to search/list LTM virtual by (partial) destination?

I'm in need of the ability to find one or more virtual servers in the active LTM configuration which have a specified IP as their destination; per the iControl REST documentation it says they support the oData $filter spec - with the caveat that they also only support the 'eq' operator... upon further investigation it seems the rest api also only supports $filter against the 'partition' field.

 

Does anyone have a good method then to query/filter a query of all virtual servers? For example, I want to do something like this:

 

Instead of: /mgmt/tm/ltm/virtual/?$select=name,destination <- this gives what I need, but gives whole list all the time – takes ~20+ seconds to send/parse because we have thousands of virtuals

 

I instead need a simple way to get the above, but filter it like: /mgmt/tm/ltm/virtual/?$select=name,destination&$filter=substring(’10.20.30.239’,destination)%20eq%20true

 

(the intent being, give me a filtered list where destination has this IP address in it)

 

I'm open to any suggestions including alternate methods at this point. Please let me know.
