The Discrete-Time Integrator block can be configured as an accumulator.

For continuous system, feed your signal to an Integrator block.
For discrete system, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.

using a Sum block and a Unit Delay block, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.

Use the discrete-time integrator block for discrete systems
