Feature Filter api meetings metrics request

We are facing some problems about connection_type from users.
I need to get all user who attended a meeting that connection_type = “SSL+Proxy”.

what I’m doing
First I get a list of meeting that happened in an time interval ( GET # /metrics/meetings),
Second for each meeting I’m doing a get participants, passing the meetingID (GET /metrics/meetings/{meetingId}/participants)
Third I check the users that their connection_type = “SSL + Proxy”

The big problem here is the number of request that I need to do.

I would like a filter feature capability to apply in the api request just to get the users that connection type was ‘SSL + proxy’ instead of get all the user from all meetings and handle by myself
