Increase number of lines on the 'My Assigned Test Sets' widget

I use the 'My Assigned Test Sets' filter on the My Page dashboard, I find it really useful to work from that page.  However I've noticed the limit of Test Sets is 50, so I don't don't see all the Test Sets assigned to me. I am aware there are other ways of seeing Test Sets, but this is purely a question related to the My Page widget. 

The 'My Assigned Test Cases' filter allows me to add more than 50!   Can the lines be increased, is it a setting my Admin can change? For all widgets I'd love to see a 'Sort', or 'Order By' option.  Widgets with filters would be even better! 

Thanks
