No (intentionally not). Because one might *want* to have different settings in
the childs.

In this case, I'd suggest to put the preamble's content into a file
"mypreamble.tex" which is saved in the folder of the LyX files, and put
\input{mypreamble.tex} into the preamble of each file (master and childs).
This way, you only need to do changes/additions in one central place.
