Hello @kervis
Unfortunately, this is totally up to the developer of the Gutenberg plugin to offer such options. Blocksy does not have any building tools for now, but we’re working on preparing our own solution as well and be sure that we will take into consideration every request that we’ve had from our users.
For now, I think it’s best to contact Stackable’s support for this one, as they know their product in and out and they will be able to point you in the right direction.
Hope this makes sense.
Thanks
