gINT Input View: Freezing Multiple Columns

In gINT input view, by default, the column of the Index field is frozen in position (typically "depth"  in the "sample"  table). That is, that column is always first in the order, and if there are too many or too wide of additional columns that require scrolling right to reveal them, the index column will remain in view. It is frozen in view.

How can I assign additional columns this "frozen" quality?

In addition to the index column "depth", I want to freeze columns "sample type" and "sample number" so that they remain in view when the window is scrolled to reveal columns in the table that extend beyond the window's view.
