Add time slots with mobile app

I can only add a time slot to a new or existing work order on the desktop web version. We need to be able to add a time slot on the mobile app android and IOS when in the field. Adding a note for my field techs with the time slot is not feasible for our business and scheduling purpose. I spoke with ECI Bolt support this morning and they stated this feature is not yet available. Please add the option to mobile app android and IOS as well so I can create, edit or add a time slot to work orders. Thank you
