The above answer from Adonio is good to rewrite the index for events at indextime using regexes, but if will have a parsing cost for each events.

Another option, if you can split your inputs is to create one udp port input for each index destination.
And have each syslog server send to a specific port.

example :

[udp://7877]  
connection_host = dns
index=index1 
sourcetype=mysyslogsourcetype


[udp://7878]  
connection_host = dns
index=index2
sourcetype=mysyslogsourcetype

[udp://7879]  
connection_host = dns
index=index3
sourcetype=mysyslogsourcetype
