Can filament bind the vertex buffer and index buffer only once in Vulkan backend?

[DOUBLE-RHH]

On lines 1715 to 1727 of the VulkanDriver.cpp :

// Next bind the vertex buffers and index buffer. One potential performance improvement is to
// avoid rebinding these if they are already bound, but since we do not (yet) support subranges
// it would be rare for a client to make consecutive draw calls with the same render primitive.
vkCmdBindVertexBuffers(cmdbuffer, 0, bufferCount, buffers, offsets);
vkCmdBindIndexBuffer(cmdbuffer, prim.indexBuffer->buffer.getGpuBuffer(), 0,
        prim.indexBuffer->indexType);

// Finally, make the actual draw call. TODO: support subranges
const uint32_t indexCount = prim.count;
const uint32_t firstIndex = prim.offset / prim.indexBuffer->elementSize;
const int32_t vertexOffset = 0;
const uint32_t firstInstId = 0;
vkCmdDrawIndexed(cmdbuffer, indexCount, instanceCount, firstIndex, vertexOffset, firstInstId);

Is the Api vkCmdDrawIndexed means filament support subranges ? If I use VK_PRIMITIVE_TOPOLOGY_TIRANGLE_LIST as the render primitive, can I bind the vertex buffer and index buffer only once?
