如何添加.到Word中书签的名称

因此，我正在使用Word创建模板，以使用Java中的XDocReport生成.pdf.我遇到的问题是，当我在Word中向图像添加书签时，允许的名称不能包含.". ，例如，我无法命名书签estimate2.Photo，这是将变量正确映射到要传递的虚拟对象所需的名称.我的问题是以下内容，有什么办法可以更改此默认Word行为，以便它允许我添加包含特殊字符(如")的书签. ?

So i am using Word to create a template for the generation of a .pdf using XDocReport in Java. The problem i have encountered is that when i add a bookmark to an image in Word the allowed names cannot contain "." , for example i cannot name the bookmark estimate2.Photo , which is the name needed to correctly map the variable to the virtual object being passed. My question is the following, is there any way i can alter this default Word behaviour in order for it to allow me to add bookmarks that contain special characters like "." ?
