Hi Jim,

Yes there is. You can indeed use the AWIPS pil to parse them out. Let me 
how you an example from my pqact.conf from this product:

# State max/min temperature and precipitation table.
WMO     ^ABUS21 (....) ([0-3][0-9])([0-2][0-9]).*/p[RS]TP
        FILE    domestic/databases/ABUS21.(\2:yy)(\2:mmm)\2
WMO     ^ABUS21 (....) ([0-3][0-9])([0-2][0-9]).*/p[RS]TP
        EXEC    make_index domestic/databases/ABUS21.(\2:yy)(\2:mmm)\2 \1 
(\2:yy)

The ".*/p" tells the LDM to look at the AWIPS pil for a pattern. Add AWIPS 
pills after this phrase to pick what you want. As you can see, I am 
picking up both the RTP and STP products, sent under the same WMO header
currently. Now then....

WMO     ^ASUS63 (....) ([0-3][0-9])([0-2][0-9]).*/pRTP
        FILE    domestic/databases/ABUS63.(\2:yy)(\2:mmm)\2

This picks 'em all up. Want just the ones you want?

WMO     ^ASUS63 (KDTX) ([0-3][0-9])([0-2][0-9]).*/pRTPMI
        FILE    domestic/databases/ASUS63.(\2:yy)(\2:mmm)\2

WMO     ^ASUS63 (KDTX) ([0-3][0-9])([0-2][0-9]).*/pRTPAPX
        FILE    domestic/databases/ASUS63.(\2:yy)(\2:mmm)\2

I do this anyway right now for a climate list I run for these two products 
from KLOT. 

Last year I did this with virtually all products in my pqact.conf, because 
numerous products are already sent under the same WMO header, and more 
will be done that way in the future. The only way to discriminate will be 
that AWIPS pil.
