Sync from non-primary

Hello everyone,

I am facing an issue where a secondary member of a 5-node replica-set always elects primary as a sync-source, having an specialized internal setup, this is not fit for our environment, and I was wondering if I can manaully setup a mechanism that will force sync from a non-primary member (the member ofcourse if eligible to be a sync source). We are using 4.2 version of MongoDB

Thanks everyone!
