WiX Toolset Extension: How to make an order of a Custom Action configurable?

Question

I am in progress with a custom WiX Toolset Extension and would like to know, if it is possible to make a custom action's order configurable?

For example, I have two actions:

1. CreateFolder Custom Action:

   CustomAction Id="CreateFolder" BinaryKey="My.Ext.CA" DllEntry="CreateFolder" Execute="deferred"

2. ExecuteSql Custom Action:

   CustomAction Id="ExecuteSql" BinaryKey="My.Ext.CA" DllEntry="ExecuteSql" Execute="deferred"

They are placed in the InstallExecuteSequence in the next order:

<InstallExecuteSequence>
            <Custom Action="CreateFolder" After="InstallValidate">
                NOT Installed
            </Custom>

            <Custom Action="ExecuteSql" Before="InstallFinalize">
                NOT Installed
            </Custom>
</InstallExecuteSequence>

It works fine for executing CreateFolder CA first, and then ExecuteSql. But, in some cases it is required for WixExtension user to run ExecuteSql first, and CreateFolder comes next.

Can I somehow specify a CA order to be executed within InstallExecuteSequence and make it configurable?
