math-macro in preamble?

[Nirmal Govind]

Hi.. is there a way to include math-macros anywhere else other than 
in the main part of the lyx file? Maybe in the preamble or so? I'm 
trying to have a global math-macros file that can be included in all 
my lyx files so that I only need to update one macros file.. I tried 
putting all the math-macros in a lyx file (MathMacros.lyx) and then 
did an "Include File" in the main lyx document that I'm editing. 
Problem is that if I open this lyx document alone (with no lyx files 
that use math-macros currently open), then the macros will not 
convert to what they're supposed to look like.. they'll show up in 
ERT... is there a workaround to this? (I'm currently making sure 
that I open MathMacros.lyx before I open any of the other files.. 
hope there's some neater way of doing this).

Thanks,
