Yes I made a reference to this last week. I bought 2 tickets for a concert and you couldn't leave a single seat. If seat 1 and 2 were gone you could book 3 and 4 but not 4 and 5. It would be a great help if something like you suggest could be done. I think last week there was about 40 seats showing available in block 8 possibly and the vast majority were singles.Bit frustrating to see the single seats scattered around esp. when lots of people go with a friend or family. I know the ST holders have the right to stay where they are but shame there isn't an app or a bot (whatever that might be) so that 'casuals' buying singles or odd numbers can't be built into existing rows rather than absolute free choice to leave a gap (which is human nature tbf).
