Sometimes, I’d like to have a duplicate of a slider control in another section. Changing one slider value should change the other too. This enables me to apply the same value to different calculations in each section. So imagine 2 linked sliders - each on a different section of the Coda doc, acting in unison.
PowerBI has an excellent application of this. It allows you to have linked date filters ( which can be configured to look like a slider). Setting the value of one date range filter automatically applies that same filter on all other linked date range filters as well.
