Similarly to OUT tags, I would like to see a "Format" property in SET tags, so that we can cast numbers to text variables with a proper format.
This is needed, among other reasons, because the "Format" property of OUT tags is more powerful (has more features) than the functions provided by Windward (esp. the TEXT function). Notably, the Format of OUT tags allows the use of a locale to define the format (decimal and grouping separators), which the TEXT function does not accept.

This idea is similar to :

- https://windward.uservoice.com/forums/248503-windward-core/suggestions/31730263-support-additional-advanced-options-for-set-tags (3 votes)
Therefore I believe this encounters some interest here.

Else, at least some improvements of the TEXT function would be greatly appreciated (will submit another idea for this).
