Hi
Use the Market Locator to select the markets you need.
Make a trigger to delete markets you don't need:
Delete Market
Conditions:
Markets name contains "Match Odds and"
this will delete match odds and OU2.5 market etc.
As you mention trialling, I suggest just manually (through locator) adding a few matches to see how it goes. Also, as this trigger refreshes 7 markets (OU1.5 to OU7.5) per match, you need to be careful how you load the markets in and refresh them. Best try it with just a few games first.
Have you seen the example triggers area on the website:
