  Application of stable localized dissipative solitons as basic carriers of
information promises the significant progress in the development of new optical
communication networks. The success development of such systems requires
getting the full control over soliton waveforms. In this paper we use the
fundamental model of dissipative solitons in the form of the complex
Ginzburg-Landau equation with a potential term to demonstrate controllable
transitions between different types of coexisted waveforms of stationary and
moving dissipative solitons. Namely, we consider mutual transitions between
so-called plain (fundamental soliton), composite, and moving pulses. We found
necessary features of transverse spatial distributions of locally applied
(along the propagation distance) attractive potentials to perform those
waveform transitions. We revealed that a one-peaked symmetric potential
transits the input pulses to the plain pulse, while a two-peaked symmetric
(asymmetric) potential performs the transitions of the input pulses to the
composite (moving) pulse.
