Assignment of custom indicators with BVEC ATS System

Me and my team have been working on some new trains for OpenBVE, and we've chosen the BVEC_ATS System for our trains. We're kind of confused about assigning more than just 5 plugin states through the ATS. In the documentation, it states that Custom Indicators 1 through 5 are assigned to security keys D to H, but Custom Indicators 6 to 10 aren't assigned to anything by default. Does anyone know of a way to assign Custom Indicators 6 to 10 to any more security keys? We want to use them for more features for our trains.

Add the following section to your configuration file:

Code:

[KeyAssignments]
CustomIndicatorKey1 = D
CustomIndicatorKey2 = E
etc. etc.
