You can easily edit any existing Shared Parameter being managed within the SPM  SQL database at any time.  You can either edit individual Parameters as required or you can edit multiple parameters at the same time to effect the same change for each of them.

To do so select the required parameter(s) from the data grid then click the Edit button from the Shared Parameter Tab of the Ribbon.
