So the work around for this is pretty simple.
For the first addition, add your jam to the recipe as a boil ingredient. Now in the recipe, edit the jam and change the type to 'extract' which will enable the 'late extract boil time'. You can enter the boil time that you want to add the jam and save.
The additions during fermentation are not so easily marked with respect to the addition times. I usually add those ingredients that I will be adding during primary and occasionally secondary and then put the addition times in days (or most usually in time past peak fermentation) in the 'notes' section. This will get printed on the brew steps report which will be hanging on the fermenter.
