New to Service Desk- Customized column views in My Tickets?

I'm a former WHD Tech, new to Service Desk.  I'm the Agent, and I'm testing things out for the Requesters before we cut over and am a bit stuck.  Can a Requester customize the column view of their "My Tickets" portal list?  I see the "Add Filter" tool, but even that can't be saved for future use.  Both filters and column customization seem like no-brainer end-user features that make each person's live easier.  Are these global settings that need to be turned on somewhere?
