Macro between different documents

Hi!
I have two separate documents, and I would like to insert two different Macros.

The first one, introducing (should start when opening document), is supposed to look in doc 1, search for the next number in order (lets say its the 3rd document I create, therefor the next number should be 3) and then input number 3 in a specifik area (H2).

Then, manually, the document is filled in and finished.

The last, finishing macro, should now copy 4 different specifik data in the document that is filled in.
F9:I9 --> B (and the next empty number)
B15:C15 --> C (and the next empty number)
I5 --> D (and the next empty number)
I53 --> E (and the next empty number)

After this is filled in, this second document should be saved in a specifik place.

Than back to the first manuelly filled document, should be renamed after the input number (in this case 3) and saved on a specifik place.

Is this possible?

greetings,
Rasmus
