Making a note on the on the availability page to reflect the C19 regs and availability limitations

the UK C19 regs mean I can open some apartments to leisure guests whilst offering others to those who travel for work and other specified reasons.  

I've closed off all weekend bookings except for the 4 apartments I can let to leisure guests, but can't do this mid week. 

I need to flag the need for mid week leisure guests to either get in touch to check availability or be aware that they may get a call to either move their dates or cancel. 

Any ideas?

Thanks
