Asset Listing Pages Display Formats

I have set up an Asset Listing Page to show dates of clinics we hold in various towns, grouped by town, however in some towns clinics last 1 day and in other towns clinics last 2 days. All clinics are set up as single calendar events and are in folders according to which town they are in. Note that all clinics in any one town are the same length.


What I what to do is have one day clinics appear like 14 February 2011 and two day clinics appear like 14 & 15 February 2011.



With Asset Listing Pages is there a way of setting up different formats for assets of the same asset type according to which folder they are in?
