Partitions in Library Manager in PADS VX

Hi,

why the library Manager in PADS VX create the same partitions under PARTS, DECAL AND SYMBOL category?

For example in my access database i have more than one table for IC (e.g.: OPAMPS, ADC, ecc..) but this components can share the same decal so i want an unique decal partitions in my library manager (e.g. IC). When i create this partition (IC) under DECAL, automatically i find the same partition under PARTS and SYMBOL.

Is there a way to define different partitions under PARTS, DECAL and SYMBOL?

Thanks
