ESR objects after re-importing SWCV into ESR from SLD

We created two SWCVs in SLD and imported into ESR.

I_MYCOMP_SWCV_ONE

I_MYCOMP_SWCV_TWO

I created few design objects like DTs MTs SIs like dtA, dtB, siC in I_MYCOMP_SWCV_TWO

but later, for some reason, to enable usage of objects of I_MYCOMP_SWCV_ONE to be used/referenced in I_MYCOMP_SWCV_TWO, we had to create dependencies in sld, something like I_MYCOMP_SWCV_TWO depends on I_MYCOMP_SWCV_ONE,

after we defined the dependency in sld, the SWCVs need to be reimported into ESR, and my previous design objects dtA, dtB, siC will be lost if i reimport I_MYCOMP_SWCV_TWO

is there any wayout, in which all my previous objects will not be lost, (so that i need not re-create manually) after importing I_MYCOMP_SWCV_TWO

thanks,

Madhu.
