Allow delayed loading while editing cards

I am encountering sever performance issue when editing drillpath cards when the data amount is big.

While it is possible (and common sense) to filter the data on parent card, drillpath editing does not take parent level filter into consideration (which is fine & correct). So it ends up taking a lot of time loading the drillpath card while editing.

Please implement one of the following to avoid this problem:

-- allow delayed loading: have a "cancel loading" popup when loading of the card takes longer than a few seconds, and allow users to finish editing & manually load or save the card. It is usually easier to go through the actual drilling for validation purpose than waiting for pre-view on edit mode in such case.

-- allow user to select some sort of filter, if preview loading takes longer than a few second.  These filters SHOULD NOT be saved as part of the drillpath card though.  It is purely for quicker load of preview for editing purpose.
