Enchanting Natural Attacks

[Quintain]

I have a particular magical item in a campaign I'm playing in that essentially enchants my character's natural claw attacks (but not his natural bite attack). Is there any method I can use to simulate this in Hero Lab?

I have an archetype built that bootstraps natural attacks (which are granted via this archetype, not via the race itself), but would like to add a magical item that is able to hook into my claw attacks and modify those, but not any other natural attacks if possible.

Any ideas?

Note: The class has the potential to have more than 2 claws (able to grow limbs and add natural attacks to them like the eidolon), so the ability would need to be specific to these two natural claw attacks.

It looks like Shadow's Adjustments allows for modifications to specific weapons and in that list of "Current Weapons", you can select from said list.

Since my item applies to both attacks, can this be put in a magical item?

Along these same lines, an additional puzzle:

Is there any way to add a limb but at the same time not allow the use of evolutions on those limbs?

Example:

Modified Evolution of Limbs(Arms), lesser -- adds to the number of limbs, but they are to weak to make regular attacks.

Then there is the normal Limbs(Arms) -- wherein they are now strong enough to allow the eidolon to take natural attack evolutions, or equip them with light or one handed weapons/shields.
