Betting assistants Gruss, bet-angel etc

hi all - i'm new to all the different trading assistants but i'm looking for one that allows me to upload a large number of conditional bets within UK horse racing (back and lays)

I know you can enter conditional bets manually using Gruss but there would be simply too many to do it manually?

Also - how does it handle non runners? ie I might want to lay a horse at 6.0 but it the 1.50 fav comes out i wouldn't!!

In the off chance I get a sensible reply tks in advance
