Mirror spreadsheet into other spreadsheet

Hi all,

We have a main spreadsheet where we keep all of our projects including the budget for those projects. I would love an option where I can either share that spreadsheet, but mask certain columns (like certain viewers can only see certain columns), or duplicate that spreadsheet, but not fill in the budget columns and then share that spreadsheet. I can't hide/unhide columns as I am not the only person in this spreadsheet, so the columns might not always stay hidden.

I have also tried WorkApps, but when I make a change to the information in the Workapp, it automatically does the same change (like hide columns) in the main spreadsheet, so again (buzzer sound), not an option.

I need something where if I fill out columns A through F, this is automatically shared to another spreadsheet, and that is the version I share with the people to not see the budget. This way, when I make any changes to the "Main" Smartsheet, it automatically updates to the other "mirrored" Smartsheet.

Is there any option like this in Smartsheet's? We normally have to export to Excel, reformat the data and then share, but then this spreadsheet is immediately out of date once we do an update in Smartsheet's that won't be reflected on the Excel spreadsheet.

Any suggestions welcome.
