WCF service publishing wizard settings

Did you ever had to republish a web service over and over again? Is it fun to go through the wizard and add the methods one by one?

We were having that problem. The idea was to make a connection between SAP and Sharepoint through web services created by Biztalk. An RFC in SAP receives the request and returns the values to Sharepoint that will use them to create a page. To comunication was quick and stable, but I was losing my mind and time creating the services one by one. Let's see the process step by step with focus on Biztalk:

1. the new RFC is created in SAP (not my problem)
2. Biztalk imports reference with the SAP Adapter (easy)
3. build and deploy dll (too easy)

4. recreate service through Biztalk WCF Publishing Wizard
4.1 select Transport Type
4.2 enable Metadata endpoint
4.3 select Biztalk application
4.4 select "publish schemas"
4.5 rename Web Service
4.6 rename Web Method
4.7 define schema type for request and for response, enlarging both the columns to read the schema type
4.8 repeat 4.6 and 4.7 for every single RFC, old or new...
4.9 define namespace
4.10 define the same service location with overwrite
4.11 allowing anonymous access
4.12 press Create

5 update reference on client
6 do some new methods
7 test

The best way to reduce time on Biztalk is never to press the Finish button. Going back the settings are all there and you can deploy it again.

But there is a better way... I googled for this situation. On this blessed link I found the answers for all my problems. Well, at least for this one.
So, the deployment stores the configuration inside wwwroot. And more! It is understandable and can be edited!

I simply made a batch file to call the wizard with the parameter
cd C:\Program Files\Microsoft BizTalk Server 2006\
BtsWcfServicePublishingWizard -WcfServiceDescription=C:\Inetpub\wwwroot\BizTalkWcfService\App_Data\Temp\WcfServiceDescription.xml

and now my work is just with steps 4.3, 4.4, 4.6, 4.7, 4.9, 4.12. The annoying configuration of all old methods, and more than half the checkbox clicks are made for me.

Question: Shouldn't the wizard allow the loading of a xml file?
