Ability to Manually Update Realm

Please give us the ability to manually update our Realms, instead of forcing it. 
Many players use client-side mods, texture, and data packs; which don't update quickly (or sometimes they stop updating altogether!) . 
Having our data packs and client-side things fail can render the realm unplayable.

This often forces players to quit playing entirely, or to have to abandon a map seed and start over.  Which means all of the work and fun we have spent hours putting energy into? Is USELESS.

PLEASE: Give us the option to choose when to update our Realms!
