A button to update SKUs incrementally with new sequential number, eg, starting from 10000, or 10. Also maybe including a Prefix and suffix option, eg, Hoodie10000Cotton. Possibly an append feature to existing SKUs, adding something to the beginning or end of the pre existing SKUs. Applying SKUs to multiple products is a long tedious process that requires you to create each individual SKU for every variant, Shopify doesn't offer any options to automate this process so see it implemented within Vela would be great :)
