PPR - Ability to expand and collapse Serial Collateral in registrations

Is your feature request related to a problem? Please describe the problem & source of request.
Suggestion from Sharon via email:

May I request that we develop ability to (+-) expand and collapse serialized collateral within the registration. Where there are long lists of serialized collateral- there is much scrolling involved to get the rest of the registration (like General Collateral or to verify).

I might suggest that it keep the first 3 or so showing and then an obvious place to expand when there is more than that listed and/or collapse the list.
