Questions about the backpacks

Now that the big Starbound update is almost ready, I'm wondering if the new backpacks will have multiple upgrade slots for the higher tier ones, I already look them up on the wiki and they will function like the nanosuits (Higher tier ones retain the functions of lower tier ones).

The reason why I'm asking about the upgrade slots, so I don't need to change the upgrades on every planet or have to store extra packs, if base game doesn't have multiple slots on higher tier packs, hopefully its easy to make a mod for this feature.

For example adding Fire Protection, Poison Resist, Frost Resist, and a Tier 3 Light would be a nice universal combination for the Tier 4 backpack.

 

In the current unstable build it is still 1 augment slot.
