Default value in table field

Hello,
When creating a new field in a Tulip table, there is no posibility to determine a default value, for example, I have a master data table that contains all articles, I want to add a flag field to decide if this particular article is kind of couples or not, most articles are not couples, so I create a field named : “is_couple” and now, on each insert, have to enter the value no, instead of yes in the exact place where it should be.
The same option can be on date fields or any other type (like exists in Sql Server for example).

Thank you,
Regards,
