Feature summary
Currently Special:MultiLock only allows GET requests if no wpMethod argument is specified. That means we can not skip the search form.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
On [[:m:SRG]] we often requests to lock multiple users at once with [[:m:template:MultiLock]]. Clicking "Lock all" always leads to Special:MultiLock on the initial Search page. This step could be skipped.

Furthermore we want to prefill the wpReasonList-other text field with the request perma link just as we do for [[:m:Special:CentralAuth]] and [[:m:Special:GlobalBlock]]

Benefits (why should this be implemented?):
It would save time by skipping an unnecessary step. It would also allow us to prefill the wpReasonList-other text field and lead to more informative log messages as noone fills in the request permalink if it is not already there.
