Sure.
Just recently I completed the lvl 25 Safeguard mission and was presented with 3 choices for contacts. Ideally the info would be presented individually with each contact, however the actual panels with the contacts pictures and information are already buttons themselves, so presenting an Optional button directly on those might prove difficult. So perhaps something like this:
Underneath each button to choose a new contact there could be a line of blue text that reads "Click Here to see some of the missions this contact may offer."
Let's say, just as an example, the contacts offered to me were Ashwin Lannister, Miriam Bloechi, and Colin Larson. I click the button under each and it unhides the following text (or variations on it depending on level, faction, etc), also in blue.
Under Ashwin's button:
Ubelmann the Unknown
The Redemption of Alexander 'The Great'
Under Miriam's button:
The Scroll of Tielekku
Find the Pantheon: Rescue the Mystics
Under Colin's button:
The Freaklympics
I think with some time I could actually make a mock up to illustrate, but is my description pretty clear?
