Hi, i want to add unique index on two fields but only if one of them is available.

for example:

for a model with email and network field:

@Index(['email', 'network'], {
  unique: true,
  where: 'account.email IS NOT NULL',
})

Only create this composite unique index if email is not null.

Expected from documentation here:

https://gorm.io/docs/indexes.html

Do we have this feature or not? How can i go about it?

use same index name for two fields with the where tag.
