Increasing access to a race's favoured class options

[Bellona]

I'm experimenting with the race building options, both under the Background tab (using the ARG and related options) and in the HL Editor (which I don't find easy to use).

One thing that I'd like to change is which favoured class options are available to a particular race. For example, a half-elf could also draw upon both the elf and human options (likewise a half-orc could draw upon both the orc and human options), and an elf could draw upon both the elf and half-elf options and maybe the human ones too (humans always seem the get the best stuff). Basically, for each race I want to open the pool of options so that they can choose from two or three races' options.

Does anyone have any suggestions as to how to accomplish this with Hero Lab - without being a coding deity?
