"Export Operation" to Studio project removes all pre-existing operations

A Studio project with already some operations declared (in "Setttings & Versioning" -> "Registries" -> "Automation operations"). The operation used by the Template Rendering plugin for example.

Have a plug-in in NUxeo IDE, with one operation. Bind your studio project to this plugin, then in

/Studio Projects/

, right-click and select "Nuxeo" -> "Export operations"

=> The exported operation(s) cxompletely remove the existing one
=> Operation chains uising these operations are broken, red flags everywhere

Expected behavior: The IDE should merge the operations:
-> Check this if this operation already exist. If yes, replace it
-> If no, just add it
