Pdfrw method to change Annotation Name #252

Hi!

Been looking around the documentation, but cant find anything relative to this, so i will ask:

There is a method or function to save a new Name for a listed Annotation?

That Textbox has this Name: Given Name Text Box and i need a way to change that name to whatever i need, like Test1.

`pdf = pdfrw.PdfReader(file_path)
for page in pdf.pages:
annotations = page['/Annots']
if annotations is None:
continue

for annotation in annotations:
    if annotation['/Subtype']=='/Widget':
        if annotation['/T']:
            key = annotation['/T'].to_unicode()
            print (key)

`
With that code ive got all the Names, but i miss something to update that Names with pdfrw.
Is this possible or im asking something can be done with this library?

thanks to anyone spare some time to answer this!
