Can I apply free shipping over a certain price when coupon used

[oavs]

Hi

I want to know if this is possible and how when for example

Product total value as below
$400 - 10% Coupon = Final Total $360 >> Apply Free shipping
$334 - 10% Coupon = Final Total $300.6 >> Apply Free shipping
$300 - 10% Coupon = Final Total $270 >> No free shipping

I am using Table Shipping method with items over $300 free shipping
50:10,100:12.00,150:14,200:16,250:18,299.99:20,330.0:0

Order Totals Module
Shipping
Free Shipping For Orders Over > $AUD300.00

Thank you
