Summary

Is it possible to add further filters to the options available when searching for candidates?

Hi, 

We have a scenario in our Public Sector implementation where positions are made redundant due to periodic re-organisation. The people occupying the positions are then put into a "Re-deployment Pool", so that they have Recruiter visibility who can give them a preference for re-deployment. 

This can be supported by expanding the Candidate Search filters, e.g. by adding commonly used assignment fields such as Assignment Status, Assignment Category or Grade. Please see this idea and upvote if you can ... OR if there is an alternate solution you have used to meet this requirement, could you please share?
