ALLEGRO如何更改元件位号和网络名？

我来详细说下我是怎么得来这些的吧
我想两快PCB和在一起，利用sub-drawing 功能，（元件库已合并），发现被导入的PCB版元件序号都变成了“C*、R*、U*”，并且出现如下信息：
Clipboard Paste Session Started at Aug 14 10:11:04 2008

Unable to paste the symbol - ("TII_182" "PACKAGE" "J1")

最后发现网络名也变成了dummy net ，我尝试把logic enable打开，利用txt edit 功能竟然用不了
，在其它上面例如把R1变成R2是可以的，现在都是R*,提示can't change the refdes of anassigned component,, 然后利用assign refdes和auto rename refdes也无法更改位号
以上请问到底该如何改?

楼上，这个是没法改变的。除非你网表里面有这个期间和这个网络。
一般如果按照这种方法复用模块。可以使用swap交换期间即可。

网表里确实没有，听别人也说用SWAP ，不知道详细步骤，求教~
