How to allow a policy to run more than 24 hours yet also have a specific start time - want to avoid status 196

I have some VMware intelligent backup policies that run every other day (some odd days, some even days).  The policies have a start time of 18:00 and they close 23 hours late. 

Depending on the mix of jobs sometimes all the jobs in the policy do not complete and the remaining ones cancel with status 196.  But I dont ever want a submitted job to not run - its OK if they run beyond 23 hours.

I tried changing the window for the policy to include all 24 hours but then the policy kicks in at 00:00 - which I dont want. I want to keep my specified start time.

How can I have a specific start time and yet also avoid 196's?
