Redmine

Is it possible to have a custom field which belongs to multiple type?
One situation is that when create one New Issue and need to enter F/W version
The F/W version could be a well known released F/W version or a dynamic daily build version
For a released F/W version, It could have the type of "List".
For a dynamic daily build version, it could be the type of "text"

Or if there is an existed feature can resolve this situation, please kindly let me know

Thanks
