[Modding][Question/Request] Terraforming

Is there a simpler way to have an improvement that can be build more than one time, than duplicate the same improvement 4 times in the improvements file?

Other than an "all or nothing" way of fonctioning:

<IsColonyUnique>true</IsColonyUnique>

For more flexibility:

<LimitForNumberOfImprovement>1</LimitForNumberOfImprovement>

<LimitForNumberOfImprovement>4</LimitForNumberOfImprovement>



***** If that is not possible, consider it as a request. *****
