Last projects processed in Project Builder

Hi experts,

We all know that the last five projects processed using the project builder will be stored in the worklist of the project builder. Currently this is a standard SAP functionality where the processed projects are stored under the userID

My question:

1. Is there a way to increase the number of projects in that list?

2. Where these informations are stored? I know that this is userID specific but dont know where.

Any input is welcome.
