Ability to update just changed field for SharePoint items

[MikaelSvenson]

When adding the "Update SharePoint item" action you have to specify values for all required fields. If you're not changing them you still need to fetch the item first in order to provide values for the fields.

It would be useful if the update SP item action only updated fields you provide a value for, effectivly doing a MERGE.

Unless I'm not fully understanding something...this strikes me as critically needed for Flow. Being forced to update required fields essentially backs us into a corner where we could easily be triggering our same workflows again based on fields being "modified" that we didn't even want or need to update.

I'd like the ability to only update a single or perhaps couple fields within a sharepoint list item.

The current process is VERY painful, I have to get the existing list item, then update the list item and set all the properties to their old value with just the one or two properties modified as I desired.  This is especially painful for 20-30 property lists.

When updating, consider a default value of "existing value" and only when I add something to the field, or when add a dynamic content does it actually modify the value.

It's also worth pointing out, if I add a field to a list, this method wouldn't break the flow or the field in the list if I forget/don't update the flow to support that field.

I like the idea of making the default choice for each filed "existing value".  This means I could just use update the field(s) that I want to.  It is a lot of trouble and annoyance to have to go in and set each field to its current value.

Please allow option to only update specified fields as to not destroy the items version history.
