Writer-tools-(letter) - edit document or personalise (merged documents)

[altair]

Hello!
If I, in letter form, try to make changes in edit document or personalise document

(tools - mail merge wizzard-1. select starting document=use the current document-2. select document type=letter-

then I CAN’T SAVE THE CHANGES!!!
I have to do the whole whole job form beginning and that consumes too much time!
Please, is there any way to shorten that procedure?
If I JUST go to edit document and make changes THEY ARE SIMPY NO WAY FOR THEM TO BE SAVED, or?

Many thanks for any hints!!!

I would like to add some text in edit document, which woudld be worth for all recipients, and then to get some messages in personalise that woudld appear just in letters fr particualr person.

Hi altair, what changes do you want to do?

[altair]

If I have tools-mail merge wizzard- letter- and want to change sth in edit document, any informations that would be written for all the letters, then when I cahnge it in edit documents, i cannot save it.

What if I have to change a detail in a document containing 1000 or more letters?
I cann ot afford to change that “by feet” i mean from one letter to another, there must be faster way.

Please, can somone help?
