Can you describe the use case for this?

[alirezavalizade]

Sure, Sometimes i need to change value of a field but also need to keep the current values of form,
for example:

initialize({
  posts: 'a value'
})

If i use this other fields will lose their values. But i need to keep my current values and just change one field. and also i don't want to set values in state on changing the form. I know it's possible using change method in finalForm state but sometimes need to this. It's nice to have it.
Take a look at this sandbox please

[erikras]

Well, this could be accomplished like this:

You have all the information you need to initialize with all the values.

@erikras Thanks for your reply, Yes i agree it, but really sometimes need to access current values for initialize the form. I can create another Sandbox,
