Preset <check> to set several keys in one check

[anonymous]

I am writing very complexe presets for extremely complex tagging schemes, and have seen the need to set several keys in one check. I would like something like this:

<check text="My check" default="off">

<check_entry key="my_first_key" value_on="foo" value_off="bar"/>
<check_entry key="my_second_key" value_on="bar" value_off="foo"/>

</check>

I have several places in my preset a set of different keys that have fixed values depending on what I check, currently I have done that as several checks after each other, but find this a little inconviniente as all the values depend on each other.
