LibreOffice Writer is missing an important feature; A page counts like field 
which counts pages of a specific style only instead of counting all the pages 
of the whole document. This feature would be very useful.

Sometimes users want to or are required to have different sections in their 
document with page numbering like this: 

Page X of Y, 

where X is a page number and Y is a page count for that specific section. For 
example:

Appendix 1 page 3 of 8
Appendix 2 page 1 of 3
Appendix 3 page 5 of 6

Currently, implementing the example above is not as simple as it should be. One 
way is to use bookmarks and cross-references like this:

1. Make a bookmark on the last line of a style: Insert > Bookmark

2. Name it like "LastPageSTYLENAME" where STYLENAME is the name of the corresponding style.

3. Make a cross-reference to it where you want the "page count for style field" 
to be: Insert > Cross-reference

4. Select type "Bookmark", select the bookmark you made, select "Page" for the 
"Insert reference to" option and click insert.

This is not that hard to do when you know how, but it is tiresome. Also, many 
users don't know how to do this workaround. A simple field would be much better: 

Insert > Fields > Page Count for style

Users would select a place where they want this field to appear (a header most 
likely but not always), select "Page Count for style" in the menu and, from the 
opening window, select a style upon which the page count field should operate. 
The options should be something like this:

 () this style (default) 

 () other style  [=========]

 () other styles [=========]

where () is a radio button and [=========] is a dropdown panel where all the styles 
used in the corresponding document are listed. 

It is useful to be able to select the style(s) the page count field should operate 
with. For example, users might need to tell the reader how many appendix pages they 
have in total like this:

"My document is 132 pages long including 14 appendix pages."

Is this feature implementable?
