WCIF A Stasis Chamber

This was possibly the best exclusive expansion pack content for The Sims 3 merely for the fact that it allows you to put your sims into stasis so now grandmother could live to see her great great great grandchild or you could put them in a room with a computer and pretend you're creating new bodies for a single sim.

I do not care too much about the power suit that came with it, but perhaps someone has already made a stasis chamber to store your sims in their pods for The Sims 4. Maybe even with an option to enter create-a-sim to directly add a member to the family without ever leaving the household and entering manage world.

Anyway, does such a thing exist?
