Another day a new TeaCommerce project :)

It's a customer requirement to have a second address line.

EG: 
Street, Address: 55 Ashtree Road
Address Line 2: Stonebridge
City: Frome
Region: Somerset
Zip: BA11 2SE

So the one I'd like to add is the one in bold above.

Is there any way to add this to the order model? I have it as an order property.

The main question is how would the user of the TeaCommerce section see this data. We thought about concatenating line 1 & 2 in the shipping details for street address but are using the html api to post these values in.

I have the following as the hidden value in the form that submits the data.

<input name="properties" type="hidden" value="email:email, firstName:firstName, lastName:lastName, phone:phone, streetAddress:billingStreetAddress, streetAddress2:billingStreetAddress2, city:billingCity, state:billingState, zipCode:billingZipCode, shipping_check:shippingCheck" />

The address line 2 is then stored as a order property called "streetAddress2" but how could I concatenate them together?
