Preventative Maintenance Schedules



I am trying to use Asana for the preventative maintenance schedule in my manufacturing plant. The “periodically” setting in recurring tasks works very well for items that have less than a month but some items are irregular. For example, I have one item that requires cleaning every 35 days (5 weeks). I don’t want to do the “repeat every 5 weeks” option because sometimes the PM gets delayed or moved up in the schedule and to my understanding, the weekly option doesn’t move according to the task completion date like the “periodically” version does. I’m wondering if someone knows a workaround or if Asana can change it to be a text field that allows me to enter more than 30 days rather than a drop-down menu.
