I have ANSI MTP3/ANSI SCCP on one SS7 link for the A-interface

ITU MTP3/ITU SCCP/ANSI TCAP on another SS7 link for the ANSI MAP interface 
(MSC to whatever, MC/HLR, etc.).
Currently the SCCP dissector uses the extern 'mtp3_standard' provided by the MTP3 dissector. Obviously this causes a problem with the configuration 
above.
Because both links are in one capture? (If they're in separate captures, you'd change the setting before or after reading in a file.)
If so, then you'd need some way of making that a per-link property, which would need
1) a mechanism for setting non-global properties through the UI, if it can't be determined from the traffic; 

	2) a mechanism for specifying the link.
