Customize checklist

Currently the checklist under the client portal is too rigid. It would be nice to be able to edit the timeline of the checklist. As it is right now, it only allows editing the item and not the timeframe of the item. One Month Before, One Week Before, One Day Before - these are not realistic to everyone's workflow. I often book a wedding couple a year in advance and would like the checklist to reflect that. So it would be nice to have a checklist that is fully customizable. Then being able to save that checklist template for future use as well.
