Can I change settings for a custom field set for participants without losing any data?

I have a custom field set that is currently configured to be used for participants. When it was set up it was configured to be targeted to just a couple of events. We now want to make this field set available for any event.

When I go into the settings for the custom field set and click on "Any" in the field labelled "Used for Participants (Event name)" Civi throws up a big warning message:

"Warning: You have chosen to remove one or more subtypes. This will cause any custom data records associated with those subtypes to be removed as long as the contact does not have a contact subtype still selected."

In practice I don't think I am removing anything, and in any event I don't actually understand what this warning means, but I can see why the alert is there.

So my question is: "Can I select the 'Any' option in this field - and by so doing deselect those specific events that were previously selected - without deleting any records?
