Is there a way for Xcelsius to only select non blank cells in the excel model, where the non blank cells are dynamically changing over time?

I mean this as an alternative to preselecting data in the model, which I can make do what I am asking.

We are investigating a means to have Xcelsius only search for, and display the non blank cells in the excel model when loading.  This is as a means to reduce load times when running the preview of the dashboard model, and only displaying the non blank data.

This has been a huge source of frustration for me.  I'm at the point now where I am simply wondering if Xcelsius can even do this or not.  Preselecting isn't exactly "dynamic"

Thanks all.
