Another possibilty is give to all items a tevent like: e_ItemID_sysmessage
Putting TEVENTS = e_ItemID_sysmessage in the ITEMDEF definition, below TYPE, for example.

And later write a single file [TYPEDEF e_ItemUD_sysmessage], with all the descriptions, much cleaner in my opinion.

[TYPEDEF e_ItemUD_sysmessage]

ON=@DCLICK

IF (<DEFNAME> == i_bottle_medium_empty)
Your code
ELSEIF (<DEFNAME> == i_hammer_smith)
Your code
...
...
..
ENDIF

It´s still a colossal work, but you will have everything in a single file.
