Can you sync and float the maximum of Y and Y2 axes (Bar-Line chart)?

[crawfe]

Hi. I would like to sync my Y and Y2 axes in Float (max = Auto) mode. Is there a feature or a work-around for this?  Often you need to visualize the impact of the primary Y axis on the secondary (Y2) axis, on the same scale. You can arbitrarily set both axes' maximum. But when a slicer drastically reduces the size of the data, the resulting chart shrinks too much to be usable. (This seems like the feature should be a checkbox!) Thanks!

...I found a solution that worked (It seemed that it took a couple of times on/off with the secopndary axis button to unscramble a frozen setting).  Turn secondary axis on; set align zeros to on, turn off secondary axis. Set both min/max to auto.  My line scale now does follow my columns scale. . I post it here for reference....
