Display Page Function Groups/Sub Item

It would be great, if you could create a function group/Sub items for a display page item (gauge/chart/Video feed, ect).  
Like for a gauge that you want to use on multiple pages.  
It would be nice if you can create a image that is x pixels by y.   
Do all of the controls and images for it, and then copy and paste that 1 item to multiple pages.   

Something like the Base page feature you have, but for smaller items to use in multiple places, so you only have to manage 1 version of it.
