I need to have different values of "Maximum Total Concurrent Builds" on differetn jobs on one category.
Global "Maximum Total Concurrent Builds" is always used. Jobs "Maximum Total Concurrent Builds" is not used.

Description of field in jenkings GUI:
The maximum number of concurrent builds of this project (or category) to be allowed to run at any one time, across all nodes.

https://github.com/jenkinsci/throttle-concurrent-builds-plugin:
Throttle this project as part of one or more categories
For this option you should specify enabled categories using checkboxes
Maximum Total Concurrent Builds and Maximum Concurrent Builds Per Node fields will be ignored

So is this expected to work or not?
