In the current version there is no button for this, but a hidden shortcut exists: open the empty target group's edit page and add ?copyfrom=<source group ID> to the address (e.g. /admin/plansgroups/12?copyfrom=7). Sprwt then duplicates every active plan of the source group for your current kitchen location — with its price rows, delivery days, categories, surcharge allowance and visibility — into the target group and prints "DONE". If the target group already has plans the copy is refused (with a raw, non-customer-facing error message).

Two things it does not copy at the plan level: the Portion Model (Custom plans come across set to Preset) and settings like the plan description, auto-select, allow-swap and hide-from-customers — only price-row fields (including a Custom row's stored portion mix) are duplicated. Because the copy also sets every new plan to active, review each one afterwards, and be aware a copied Custom plan can end up with leftover, no-longer-visible portion-mix data (see "Can I switch an existing plan between Preset and Custom?"). Treat this as an unofficial feature and test it on a staging site first.
