Reopening - social distance seating plan

Hi all

hope you are keeping well. We've been asked about whether upon reopening we can change our seating plans to operate social distancing so leave gaps between bookings & keep rows free. This is much easier for shows not set up yet, but we're struggling to see how this is possible for shows already on sale or set up. I was just wondering if anyone has even starting thinking about reopening yet & what they would do?

Thanks!

Lucy
