Can we assign "maximum queue size" to different service number ?

We saw there is maximum queue size you can set for your account

it was 50 at the maximum but since we have 10 numbers are being currently used for our customer call service, and we often times heard that our callers are automatically disconnected and directed to voice mail when there was more than 50 callers in queue.

its actually affecting the quality of our service provided to our customer and we would like to figure things out for them

the only way we can hand this is from zendesk system, there should be maximum queue size we can assign to each numbers so that each service number has more than 50 callers that can be waiting for connection to our agents or increase at least from "50" to "100"

your answer and feasibility on this will be highly appreciated

thanks,
