Feature Request: Bulk Ticket Management and Usage Tracking

We would like customers to be able to purchase multiple tickets (for example, 100 tickets) and choose how many they want to use. It would be a hassle if they received 100 emails, right?

In that regard, we would like to request the implementation of the following two features.

1. Bulk ticket management and the ability to "use X number of tickets at once,"

2. The ability to check ticket usage status on My Page.
