Does it support Pricing fields?

Hello.
I’m making a reservation post using this plugin.
In the form, there are couple product fields which include price. Also there is a coupon field.

I can see the ‘custom fields’ under ‘post fields’ section, but I cannot see any price related options in custom fields options.

Can anyone help me? Thanks in advance.
