Good idea but you're right, if the default value is an expression such as a the next serial value, it will need to be executed first. If Execute doesn't return the interpreted value, I don't know of a way to make it work..

Well (thinking it thoroughly) it won't work at all as is. It will just
put the source code of the default expression but you would need to
*interpret* it first.
Looked for a way to do this (without `EXECUTE') but couldn't find it. Sorry.
