Request for elapsed time in dependency lags/leads to allow for weekend work

I'm working with a biotech team and its extremely common that biological research activities can't stick to a regular 5d/40hr schedule and some tasks will end up on weekends. This can be done in simple cases with elapsed days (e1d etc). But frequently I need to set a dependency that's one or more days following another activity (XXfs+1d) so that it can properly fall into a weekend. MSProject allows you to use elapsed days in lags and leads but elapsed days don't work at all in leads/lags in Smartsheet. This is really frustrating. I see that there are multiple other users who've pointed out this same need - could smartsheet expedite this improvement please?

Many thanks!
